Well, probably - although often these things turn out to be due to the different architectures of XEmacs and Emacs. The key here is to find out what the problem actually is. For instance it takes roughly 11 seconds to load JDE on my PIII 850 and 5 seconds to load and fontify a 1500 line Java file. I suspect that the original problem is not so much the speed of JDE but just the time it takes JDE to load on XEmacs. This is on a cygwin compiled XEmacs which is known to be slower than a natively compiled XEmacs. I believe these problems have been fixed. Certainly these things work well enough for me. andy
